Question

PLS HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Which statement is true?A. 25-15×4-3×2=30B. 24-15×(4-3)×2=30C. (24-15)×4-3×2=30D. (24-15)×4-3×2=66

Answer 1

The correct statement is C.

To notice this, we need to remember the correct order of operations:

• Parentheses

,

• Powers and roots

,

• Multiplications and divisions

,

• Additions and subtractions.

Using this ordering we have for each operation:

A.

$\begin{gathered} 25-15\times4-3\times2=25-60-6 \\ =-41 \end{gathered}$

B.

$\begin{gathered} 24-15\times(4-3)\times2=24-15\times1\times2 \\ =24-30 \\ =-6 \end{gathered}$

C.

$\begin{gathered} (24-15)\times4-3\times2=9\times4-3\times2 \\ =36-6 \\ =30 \end{gathered}$

D.

$\begin{gathered} (24-15)\times4-3\times2=9\times4-3\times2 \\ =36-6 \\ =30 \end{gathered}$

Hence the only correct result in the operations is the one given in option C.
